To all whom fit may' concern:

Be it known that I, CHARLS HENRY BACON, a citizen of the United States, residing at Paulsboro, in the county of Gloucester and State of New Jersey, have invented a new and useful Device for Operating Flushing-Valves, of which the following is a specification.

1 his invention relates to water closets and has reference to devices for operating the liushing valves common in closets provided with a flushing tank.

One object of the invention is to improve the general form and construction of such a device.

Another object of the invention is to provide an improved form of latch lever to be used in such devices.

The invention consists in general, of a device of the character described comprising a bowl, a flushing tank, a flushing pipe connecting the tank and bowl, a suitable valve for the flushing pipe, and means for actuating the valve.

With the above and other objects in view the invention consists of certain novel arrangements of details and the combination of parts herein after described, illustrated in the accompanying` drawings and specifically set forth in the claims.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and: Figure 1 is a side elevation partly in section of a water closet and the device attached thereto.- Fig. 2 is a top plan view of the closet showing the manner of attaching the device to the closet seat. Fig. 3 is a perspective detail of the lever fulcrum. Fig. 4 is a similar view of the rod guide.

The numeral 10 indicates a. closet bowl which may be of any desired form or style. Upon this closet bowl is mounted the seat having a portion 11 rigidly fixed thereto and a portion 12 hinged to the portion 11 so that the same may be raised or dropped. The bowl 10 is cut away as at 13 for a purpose hereinafter to be described and is further provided with the usual spud 14 to receive the end of the flushing pipe 15. The upper end of the flushing pipe is held to a valve seat 16 by a tank union 17. A tank 18 being arranged with an opening 19 through which passes the valve portion 16 of the tank' union. The tank 18 is provided with a back or rear wall 19 having a longitudinal rabbet therein. At the upper end of the rabbeted portion 20 is a guide 21. The rabbet 20 is provided at its lower end with an opening 22 through the bottom Vof the tank. Through the opening 22 and lying in the rabbet 20 is a square rod 23 having a downwardly extending continuation circular in cross section as at 24 and being provided with a collar 25 suitably positioned thereon. At the lower end of the downwardly extending portion 24 is provided a flattened portion 26, having a plurality of holes 27 therethrough. Arms 28 are rigidly attached to the hinge portion 12 of the seat and pass around the pipe 15 and are there brought together to lie one on either side of the flattened portion 26 of the rod 24. These arms are provided at the outer end with a suitable aperture and a bolt 29 passes there through to connect the arms to one of the ,openings 27.

Surrounding that portion of the rod 24 immediately below the tank 18 is the casing 30 attached to said tank in any suitable manner. rI`hek lower end of the casing 3() is closed as indicated at 31 by a suitable head having an aperture 32 there through to permit the passage of the rod 24. The collar 25, before referred to, lies within this casing and the length of the casing is such that when the seat is raised to its fullest height the collar will be substantially in contact with the head 31. A spring 33 is held between the collar 25 and the upper end of the casing 30. This spring is so arranged as to strength that it will normally hold the front portion 12 of the seat raised. In order to accomplish this it is preferred that the spring have an excess strength of such degree that it will require a pressure of substantially 15 pounds upon the seat to force thereof. The back wall 42 of the 'fulcriini' box 34 is cut away to permit this resilient bar moving forward so that the hook 41 may engage the lever 38. The end of the lever opposite to that one which is beveled is positioned substantially over the valve seat 16 and carries pivotally attached thereto a link 43 having a loop 44 at its lower end. At 45, below the loop 44, is mounted a guide. rI`his guide is here shown as mounted on a waste pipe 46 but it is obvious that the same may be, when desired, mounted against one of the walls of the tank. Aitloat valve 47 is held to position on the valve scat 16, being provided with a stem 48 passing through the guide 45 for this purpose. The upper end of the valve stern 4S is bent to form a head as indicated at 49. 'Ihe valve stem 48 passes upward through the guide 45 and:

through the loop 44 the head 49 being located above the loop, so that there is thus formed a sliding connection between the link 43 and the valve stem 48.

In the operation of this device when the closet is iised the seat is depressed. This causes the arms 2S to rise and force the rod 24 upward whereby the spring 33 is compressed between the collar 25 and the upper end of the casing 30. As the spring is compressed the upper rod of course rises and carries with it the resilient arin 40. As this arm rises beyond the back wall 42 of the fulcriim box 34 the beveled end of the latch 41 contacts with the beveled portion of the lever end 39. rIhe arm 40 is then forced back a little until the latch 41 springs over the upper side of the lever 38. lVhen the person rises the spring 33 forces the rod 23 downward and depresses the end of 39 of the lever 38. This causes the other end of the lever to rise and lifts the float valve 47 clear of the seat 1G. As soon as the valve 4T lifts from the seat 16 it rises by reason of its buoyancy toward the top of the water, the stein 43 passing upward through the guide 45 and loop 44 of the link 43. The water is then drawn off from the tank to flush the bowl, and the valve again descends. While this operation is going on the hook or latch 41 is freed from the end 39 of the lever 3b by reason of the resilient arm 4() being forced back by the back wall 42 of the fiilcriiin box 34. This permits the end of the lever carrying the link 43 to be kept in the position as shown in Fig. 1. The valve 4T is thus permitted, when the water has descended suliiciently low, to position on the valve seat 15. Water is now admitted to the tank in any desired manner,l the same not beingl necessary here to be shown, as it forms no part ofthe invention, and the valve is held firmly upon the seat by the pressure of the water on the upper hemisphere exceeding the pressure on the lower hemisphere.

v'There has thus been provided a simple and eflicient device of the character described and for the purpose specified.

It is obvious that minor changes may be made in the form and proportions of this invention without departing from the material principles thereof. It is not therefore to confine the invention to the exact forni herein shown and described, but it is wished to include all such as is properly covered in the scope of the invention.

Having thus described the invention what Yis claimed as new, is
